I was wondering what the Advanced Higher Physics course is like. I'm doing higher at the minute and am finding it TERRIBLY boring - all it is is calculations, more calculations and yet more calculations.

Physics was my fave subject at standard grade but the higher course is putting me right off!

Well i am doing AH Physics this year and its really difficult and much more indepth about the things in higher including deriving equations in an exam which isn't all that difficult but it adds to the problem

Bascally there is tons of stuff to learn that can easily swomp you i am extimated at a B at the moment where i was estimeted at an A last year (Sadly only got a B in the end but we don't talk about that anymore

If i am not here i am somewhere else

I really enjoy AH physics (call me weird if you want!)

In terms of workload it quite a bit more, but their is a lot more explanation, ie, do you know why the equations of motion are what they are? Example, given that "a" is the second derivative of s with respect to t, derive the 3 equations of linear motion. (you would integrate).

I have done unit 1 and 3 so far and I wouldn't say they are hugely difficult if you do your work, but they are a fair bit more challenging than higher physics.

The topics in unit 1 (mechanics are):
The kinematic relationships
Newton's law of special relativity
Angular motion
Rotational Dynamics
Gravitation
Simple Harmonic Motion
Wave/Particle Duality

The topics in unit 3 (wave phenomena) are:
Waves
Interference by division of amplitude
Interference by division of wave front
Polarisation

I found unit 3 easier than unit 1.

In terms of a grade I am predicted an A (which I need as part of my conditional offer for uni!) I think that is quite achievable as long as I do the work.

i have just finished Unit 2 and its really awful its about electric fields, magnetic fields , induction and other wonderful things its the hardest unit i would think but i am coming around to it after some serious studying. Of course Werlop being significantly more intelligent than me wont have any problems with it

If i am not here i am somewhere else

lol, everyone has faith in me apart from myself! I doubt I'm more intelligent than most people here, just probably more obsessive, ie I MUST get things right or it really really annoys me. Probably a bad thing, but there you go.

Our teacher has spent the last week saying that unit 2 is dead easy, but other people who did the course last year say its nasty.

It's strange, when we first learn something in physics I either totally don't understand it at all or I understand most of it straight away (mostly the first one!). Then after looking at the notes for a day or two it seems a lot easier.

I'm now off to revise some wave/particle duality

Thanks for the replies.

When it comes to not understanding anything at first : I'm usually the same - in all my subjects! I tend to learn a lot of new things when I come to revise for NABs, exams etc

AH Physics is the hardest AH i'm taking and its also the one where there is no motivation to study.

If u need the grades and can take other AH subjects (such as maths, etc) then not taking physics may probably mean a lot less work! but if u think u might enjoy it then why not.

The course is 'interesting' enough but there is a lot to learn and even more problem solving involved. its not like higher where there's around a max of 3 steps in a question. in my prelim paper there was a question that required 6 steps! needless to say, i didnt get it at all.

and werlop: unit 2 is nasty. but not as nasty as unit 1.

Does AH Physics/H Physics require knowledge from H Maths/AH Maths, like deriving equations and stuff?

yes, their are proofs of equations that require binomal expansion but really to derive equations in Physics you are just using substituation and changing the subject of the formula

Binomial Expansion?
Is this stuff in unit 3 or something?

in unit 1 to derive so formula (cant remember which) our teacher used the expansion

Oh right, i have not seen any Binomail Expansion being used to derive a forumula in Unit 1
Maybe there are other ways to do it

i am sure its on the front pages or two of the learning teaching scotland notes however those are the pages that got torn off and lost on my notes

i think i remember the binomial theorem bit as well. it may have been to do with moment of inertia(?) of different shaped objects and stuff. though i dont think its required to be learnt for the exam...

The binomial expansion can be used for the relatvistic energy calculation, eg working out

E=mc = m c + 1/2 mv ... etc

but it isn't needed for the exam.

It was something else on equations of motion i think

Hmm the only bit I can find it in was the relativistic energy section:
